This qualitative case study investigates the interaction sequences that emerge among secondary school students engaged in mathematical modelling tasks using digital technologies. The study focuses on four groups of 14–17-year-old students in southern Norway, varying in achievement levels, as they worked on two distinct mathematical modelling tasks. Task 1 involved numerical manipulation and function development based on given data, while Task 2 required qualitative decision-making without explicit numerical constraints. Recorded interactions, comprising video and screen-capture data, were analysed using thematic analysis, focusing on pseudo, asymmetrical, reactive and mutual interaction sequences. The findings indicate that Task 1 predominantly elicited asymmetrical interaction sequences, with high-performing students taking the lead in proposing solutions, reflecting limited exchange patterns. In contrast, Task 2 fostered more reactive and mutual interaction sequences, supporting balanced and equitable exchanges within groups. Additionally, group composition shaped interaction patterns: same-achievement, high-performing upper secondary groups and mixed-achievement lower secondary groups demonstrated more mutual and reactive interaction sequences across tasks, while mixed-achievement upper secondary groups exhibited more varied patterns. The study highlights how task design, group composition and digital technology use interact to influence collaborative learning dynamics in mathematical modelling.
